Bms causes
Burning mouth syndrome can result from nerve changes, dry mouth, irritation, nutritional problems, medicines, or another condition.
The short answer
Burning mouth syndrome is a burning, scalding, or tingling sensation in a normal-looking mouth, often linked to nerve changes, dry mouth, irritation, or an underlying medical problem. It commonly affects the tongue, lips, palate, or several areas together.

What is the direct answer?
What does this question mean?
The symptom may be primary, caused by altered pain signalling in oral nerves, or secondary to a condition such as dry mouth, oral yeast infection, reflux, anaemia, diabetes, or a vitamin deficiency. Toothpaste ingredients, dentures, clenching, and some medicines can also irritate tissues or reduce saliva.
What can you do next?
Note when the burning began, where it occurs, and whether foods, medicines, stress, or mouth dryness change it. Use water or sugar-free gum to support saliva, avoid tobacco and alcohol, and stop using strongly flavoured mouth products until the cause is assessed.
When should you seek dental care?
Arrange an examination if burning persists, recurs, or affects eating or sleep. Prompt care is important for swelling, ulcers that do not heal, white patches, trouble swallowing, facial weakness, or sudden breathing difficulty.
What should you ask the dentist?
Ask whether the pattern suggests dry mouth, infection, irritation, nerve-related burning, or a medical cause. Ask which medicines, blood tests, saliva tests, or oral examinations are appropriate and how treatment will be monitored.
Frequently asked questions
Can stress cause burning mouth symptoms?
Stress can amplify pain signalling and muscle tension, but persistent burning still needs assessment for oral and medical causes.
Is burning mouth caused by an allergy?
Contact irritation or allergy to a flavouring, dental material, or product is possible, but it is only one of several causes.
